Question

A=5 radical 2 b=3 radical din 5 care este mai mic ??
ajutooooooor!!!va rog azi am teza si vreau sa ma ajute cineva

Answer 1

a  = 5√2 = √(5² x 2) = √50
b = 3√5 = √(3² x 5) = √45
√45 < √50 
     b < a

Answer 2

$A=5 \sqrt{2};B=3 \sqrt{5}\\ \\A=5 \sqrt{2}=\sqrt{2\cdot5^{2} } = \sqrt{2\cdot25}} = \sqrt{50} \\ \\B=3\sqrt{5}=\sqrt{5\cdot3^{2} } = \sqrt{5\cdot9}} = \sqrt{45}$
$\sqrt{45}\ \textless \ \sqrt{50} \\ \\ A\ \textgreater \ B$
